Practical tools for measured work
Random number generator
Generate bounded random integers with optional unique results using browser crypto.
Calculate the layout, check the diagram, then print the result for the shop or jobsite.
Choose the settings and generate a fresh result. Changing settings clears the previous result.
How it works
Both range endpoints are included. Each draw uses browser crypto with rejection sampling to avoid modulo bias. The unique mode samples without replacement and shuffles the selected values.
Use whole-number bounds between −1,000,000,000 and 1,000,000,000 and request 1–1000 numbers. To select every integer from 1 through 10 once, choose minimum 1, maximum 10, quantity 10 and No repeats.
Limitations
Random results are not predictions and do not guarantee a particular long-run distribution in a short sample. Values are generated locally and are not saved between visits. No seed or replay sequence is provided.
